Onan generator exhaust

[Mike44]

Hi, I have a Onan generator with exhaust 1-5/8. I am looking for a Barb coupler 1-5/8. I need to connect a straight hose with a elbow hose. I can't seem to find a 1-5/8 coupler anywhere but I can find a 1-5/8 exhaust hose. Any help would be appreciated.

I dont have specific help, but check out pipe nipples in SS or Bronze. Sometimes they happen to coincide dimensionally with what you need.
FOr instance:
A 316 SS 1.25" pipe nipple is just 1/16" over your 1-5/8" requirement. It may fit as is or you can turn/grind the tops of the threads off to be 1-5/8". Or buy a longer one and cut the threaded ends off.

Thanks I was thinking of doing the same thing but was just hoping I would find a Barb fitting. Thanks again

What's the intended function of the fitting in question?

To join two 1-5/8 tubes together.

Check with Centek. I know they make some stuff in 1 5/8", so they may have a straight piece that would work to connect 2 hoses together.

Just be aware the longer the exhaust the larger the inside diameter,back pressure is the biggest enemy of most diesels.⛵️⚓️
